| CXM3531XR [SP4T Antenna Switch for CDMA/UMTS] |
>>Description
The CXM3531XR is a high power SP4T antenna switch for CDMA/UMTS applications.
The antenna port can be routed to either of the 4TRx ports.
The low insertion loss on transmit means increased talk time as the Tx power amplifier can be operated at a
lower output level.
Built-in decoder reduces component count and simplifies PCB layout by allowing direct connection of the
switch to digital base band control lines with the 1.8V CMOS logic levels.
The Sony GaAs JPHEMT MMIC Process is used for low insertion loss and high linearity.
(Applications: CDMA/UMTS handsets) |
